The footage is taken from a nearby balcony. An officer, dressed in a maroon polo shirt, is seen grabbing a young man as a crowd watches. Another man is lying bleeding on the ground next to them.

The officer shoots the gun six times as the camera cuts to the balcony from where the woman is filming. She can be heard screaming over the gunfire.

When the camera pans back to the street, the man is on the ground and the officer is pinning him down with his foot, as another man in a striped shirt passes him a new gun and takes the original one.

The man aims his gun at the man on the ground and five gunshots ring out as the camera shakes. The man appears to reload his gun before returning to his victim - who is still moving - to fire another bullet in his back.

According to local media, the dead men are believed to have belonged to the Gaza or Superpower gangs notorious for robberies and killings in the area. Police had reportedly been chasing the two men before the shooting took place.

Another video shows the scene from a closer vantage point, and appears to have been taken just before the above footage was captured.

It shows the other man lying on the ground and the officers and the victim arguing. The man in maroon is seen punching the boy, who then puts his hands up in surrender. The officers remove a weapon from his trousers.

If silly brats in eastleigh think they can kill because they are poor and need money, they must be dispatched to their maker PRONTO! pic.twitter.com/8Ip9yWGj8e

Inspector General of Police Joseph Boinnet condemned the violence and ordered a probe into the incident and the officers involved in the act.

“I have ordered thorough investigations on the shooting incident that occurred in Eastleigh,” he told Capital FM News. “I have seen the video and I condemn those actions. Investigations have already started and I can assure you action will be taken against officers involved.”

To some, the killings were warranted given the violence reportedly committed by the gangs.

Police commander Japheth Koome, who originally claimed the video was “not true, it was acted,” said the suspect was wanted for killing two police officers.

“I buried a corporal from Kayole yesterday. The same gangsters shot dead another officer yesterday,” he said. “Tell all gangsters out there that when they kill an officer I am ruthless and they will get it from me.”
